Expand description

Cursor information.

Implementations§

source§

impl MetaCursorRef

source

pub fn id(&self) -> u32

cursor id. an id of 0 is an invalid id and means that there is no new cursor data

source

pub fn set_id(&mut self, id: u32)

source

pub fn flags(&self) -> u32

source

pub fn set_flags(&mut self, flags: u32)

source

pub fn position(&self) -> &PointRef

position on screen

source

pub fn position_mut(&mut self) -> &mut PointRef

source

pub fn hotspot(&self) -> &PointRef

offsets for hotspot in bitmap, this field has no meaning when there is no valid bitmap (see below)

source

pub fn hotspot_mut(&mut self) -> &mut PointRef

source

pub fn bitmap_offset(&self) -> u32

offset of bitmap meta in this structure. When the offset is 0, there is no new bitmap information. When the offset is >= sizeof(struct spa_meta_cursor) there is a struct spa_meta_bitmap at the offset.

source

pub fn set_bitmap_offset(&mut self, bitmap_offset: u32)

source

pub unsafe fn bitmap(&self) -> Option<&mut MetaBitmapRef>

Cursor bitmap data with elements of type T. Returns [Some(&mut T)] or None, when bitmap data is missing.

Safety

There are no guarantees that bitmap has type T.

source

pub fn is_valid(&self) -> bool

impl From<MetaCursorRef> for spa_meta_cursor

source§

source§

impl RawWrapper for MetaCursorRef

§

type CType = spa_meta_cursor

External type
source§

fn as_raw_ptr(&self) -> *mut Self::CType

Raw ptr to the external type
source§

fn as_raw(&self) -> &Self::CType

Wrapped external value
source§

fn from_raw(raw: Self::CType) -> Self

Creates wrapper from the external value, can be use when external type has no raw pointers.
source§

unsafe fn mut_from_raw_ptr<'lft>(raw: *mut Self::CType) -> &'lft mut Self

Cast external pointer to the borrowed mutable wrapper. Panic when pointer is null. Lifetime is not reliable and should be guaranteed explicitly. Read more
source§

unsafe fn from_raw_ptr<'a>(raw: *const Self::CType) -> &'a Self

Cast external pointer to the borrowed wrapper. Panic when pointer is null. Lifetime is not reliable and should be guaranteed explicitly. Read more
source§

fn as_ptr(&self) -> *mut Self

Raw mutable pointer to Self
